Fluorescent Fungi is an Inazuma specialty in Genshin Impact found only in certain locations. Not only does it look mesmerizing, but it's also a material used to ascend certain characters, so it's important to know how to gather them.
Fluorescent Fungi was first introduced to Genshin Impact in the 2.2 update, which added the Tsurumi Island as an explorable part of Inazuma. Since its initial addition, Fluorescent Fungi has been a valuable resource since a ton of it is required for all stages of Thoma's level-up Ascension — miHoYo's newest Pyro polearm character. Here's a guide for where to find every Fluorescent Fungi in Inazuma.
Genshin Impact Fluorescent Fungus Location Guide: Where to Find
Farming for Fluorescent Fungus is relatively simple because they pretty much just concentrated around Tsurumi Island in Inazuma. As standard procedures go for items scattered across Teyvat, Fluorescent Fungus tends to sprout up in the wild.
Since they can be found as shining blue mushrooms, it is hard to miss them, especially in dark areas.
Travelers will need 168 Fluorescent Fungus to ascend Thoma to his maximum level.
